Epidemiology of swine dysentery: development and evaluation of cultural and serological methods for the detection of Treponema hyodysenteriae infection

Abstract

This material was produced from a microfilm copy of the original document. While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1. The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suqiected that the copy may have moved during exposure and thus cause a blurred image. You will find a good image of the page in the adjacent frame. 3. When a map, drawing or chart, etc., was part of the material being photographed ths photographer followed a definite method in "sectioning" the material. It is customary to begin photoing at the upper left hand comer of a large sheet and to continue photoing from left to right in equal sections with a small overlap. If necessary, sectioning is continued again-beginning below the first row and continuing on until complete. 4. The majority of users indicate that the textual content is of greatest value, however, a somewhat higher quality reproduction couid be made from "photographs" if essential to the understanding of the dissertation. Silver prints of "photographs" may be ordered at additional charge by writing the Order Department, giving the catalog number, title, author and specific pages you wish reproduced. 5. PLEASE NOTE: Some pages may have indistinct print. Filmed as received.

Immunobiology of Treponema hyodysenteriae outer membrane components

“…After pigs recover from swine dysentery and become asymptomatic they continue to pass hvodvsenteriae in their feces for up to 70 days(23).Infected mice have been shown to shed the organism for as long as 200 days. Dogs, flies, birds and rats apparently do not become infected with the organism but could serve as mechanical vectors(23,92).The most common method of introducing T.hvodvsenteriae into a herd is by asymptomatic carrier pigs. Mechanical vectors (i.e., feces, contaminated boots, coveralls or vehicle tires) may also be responsible for the transmission of T. hvodvsenteriae from herd to herd(23,92).…”

The natural spread of swine dysentery from pig to pig is by the ingestion of feces or contaminated feed.…”
